The consumer called onstar to tell them that the vehicle had not been in an accident. The operator asked the consumer were there any lights on the dash. The consumer stated the air bag light was on.

They vehicle was towed to the dealership. A week later, the consumer received a call from the dealership stating the explosion was caused by a poor design in the galleys in the floor, they went from the center of the truck to the drivers side door under a rubber mate. One of the galleys went through a rubber grommet which allowed water to leak into a compartment storing very high pressure compact cylinders for the air bag and seat belts. The water caused corrosion on the high pressure cylinders and caused the explosion. Also, the tailgate latch would not latch properly. The dealer found the pivots had seized. On cold starts, the transmission would hesitate and then a loud bang was heard. The dealer found a valve body bolt broken.

Hesitation on acceleration. While merging onto an interstate highway pressed the accelerator to rapidly increase speed but the vehicle hesitated causing me to have to continue down the shoulder and actually stop to avoid a stalled vehicle on the shoulder. I have taken my vehicle to two different dealers to investigate the hesitation on acceleration both have stated that this is normal operation for the 2007 Chevrolet Silverado. Although I didn't have an accident with this particular incident I have noticed this hesitation during normal day to day driving. This is a safety issue.
